Powerigs add force to fastening systems
One of Europe's leading fastening systems companies has updated two tooling powerigs, with significant operator benefits.
The self-locking function is created by an axial deformed slot.
The metal above the slot is set to de-pitch the threads, so when the nut is tightened onto a bolt the thread is gripped on the flank.
When fully inserted, the elasticity of metal allows the slot to press upon the male thread and provide the locking effect.
Reliable in temperatures from -50 to +450C, they can be re-used up to five times to maintain a consistent and vibration-resistant locking performance, unaffected by the intrusion of oil, petrol or other liquids and vapours.
Also available in brass or aluminium, SNEP nuts are fully certified by Network Rail in the UK (PA05/03451, 19/12/07) and SNCF in France.
Rail applications include, electrical connection to tracks and wheels, electrical lines to connection boxes, fastening wheels to wagons, rails to cement sleepers and stretcher bars; as well as on offshore platforms, mining conveyors, cranes, agricultural equipment and compressors.
